Definitions

  • the invention relates to a method for support personal mobility, with which the availability of services on end devices, which in principle at any access node for the Internet, are connected.
  • an identity e.g. B. by logical addresses, e.g. similar to the email format.
  • identifier e.g. B.
  • logical addresses e.g. similar to the email format.
  • universal i.e. none specific configured terminals
  • PCs in the hotel room, in Conference rooms or in Internet cafes, or also carried Notebooks.
  • the invention has for its object the complete Ensure support for mobility.
  • the communication connection to the UAS / PN can be made using standard procedures be set up, e.g. Point-to-point protocol PPP.
  • the terminal is assigned an IP address by the UAS / PN assigned.
  • This IP address is either that of the SA received IP address or one newly determined locally by the UAS / PN IP address. In the latter case, the UAS / PN must do an IP address translation (from the terminal to the UAS / PN
  • the PN component of the UAS / PN packs sent IP packets again and provides them with the IP address assigned by the SA as sender).
  • the UAS / PN i.e. the PN component, uses the already known principle of Mobile IP [1] to enable the participant with his terminal to use all services of the Internet as if it were the terminal connected to the HN.
  • the principle of Mobile IP is in briefly explained the following:
  • MN Mobile Node
  • HA Home Agent
  • FA Foreign Agent
  • MN Mobile Node
  • HA Home Agent
  • FA Foreign Agent
  • the MN is a terminal / terminal that connects its connection point in one Home network to another connection point in a foreign network changes, keeping the IP address.
  • the HA in Home network routes packets for the MN through a tunnel (identified by two endpoints, i.e. IP addresses), that ends at the FA continues to the MN when the MN is in the foreign network located.
  • the FA provides routing services for the MN ready: forwarding the packets coming from the HA, as well Router function for packets coming from the MN. With help of these components becomes transparent end device mobility provided.
  • the functionality of the Home agents required, which is integrated in the SA.
  • the terminal itself is a host (network computer, network node) the PN component is omitted.
  • the terminal that too is a Mobile Node after Mobile IP, and then the UAS can with regard to their functionality can be implemented on a host; the UAS function can in principle be a protected one Software process. But it could also be a separate one Give server for the UAS. Then the terminal needs one Client function for communication with the UAS.
  • the subscriber is usually in the home network (HN). If he is mobile, he would like to go from elsewhere any terminal with access to the Internet communicate with other participants (e.g. Voice over Internet) or generally use internet services. Is the Participants in a foreign network will usually be there for him a terminal or a connection is provided (e.g. PC with Dial-up option). The participant now also wants to go from there from his usual home services or explicitly access the resources in his HN. Furthermore he would also like from other participants under his general known identity can be achieved. The participant goes to this as follows:
  • the mobile subscriber logs on via a terminal to an access node of an (external) Internet service provider (ISP x). To do this, he enters his user ID, for example in the form of an email address.
  • the user ID is accepted by the UAS / PN.
  • the UAS / PN uses this (e.g. with the help of the Domain Name Service used on the Internet) to determine the address of the server agent (SA) in the home network (ISP y).
  • SA server agent
  • ISP y home network
  • the mobile subscriber is identified by the SA using a special authentication protocol.
  • an IP address is taken from the address pool that is available to the SA.
  • the SA carries the link User ID - IP address "in an association table and transmits the IP address to the UAS / PN using a special protocol. In connection with this, a specific user profile can also be transmitted.
  • the UAS / PN assigns the terminal the IP address and activates the proxy mobile node component.
  • Mobile IP Mobile IP
  • the proxy mobile node reports in Representation of the participant to the Foreign Agent and shares him the address of the SA in the home network.
  • the tunnel set up between Foreign Agent and Home Agent as well as the Source address specified by the proxy mobile node checked. Is this operation is successful, d. H.
  • the above Communication path is established, a Communication connection between UAS / PN and terminal via the access node (for example with the Standard procedure point-to-point protocol, PPP).
  • the mobile subscriber is now everyone Internet access accessible from anywhere in the world. For applications like The mobile subscriber can make telephony over the Internet can now be called at any time.
  • the terminal can also temporarily in a (to in the home network services used virtually equivalent) work environment be converted for the mobile subscriber.
  • Suitable protocols e.g. from the local area Networks for X terminals are known.
  • a target IP address is sufficient to display the graphic to redirect another terminal.
  • the mobile Participants a selection of services (video telephony, Intelligence services, etc.) as usual at home.
  • the mobile subscriber ends his activity, he logs on out of the terminal. Then the terminal is typically released again, the temporary IP address deleted and a message from the proxy mobile node to the SA in the home network deducted so that the entry in the association table can be deleted.
